3,000W 12V Pure Sine Wave Inverter for Larger RV, Van and Boat Systems
The NOVA 3K PURE turns 12V battery power into 3,000W of clean, pure sine wave AC, with 6,000W of surge headroom for motors and compressors starting up.
Pure sine wave output matters for anything with a motor, a compressor or a circuit board — laptops, microwaves, fridges, CPAP machines and power tools all run cooler and quieter on it than on modified sine. Total harmonic distortion stays <3%. It works with 12v deep-cycle and lithium (bms) batteries.
Size the battery bank to the load, not just the inverter: a 3,000W inverter can draw well over 250A from a 12V bank at full output, so cable gauge and battery discharge rating matter as much as the inverter itself. Call us on 1-332-291-6885 if you want the sizing checked.

Frequently Asked Questions
What can this inverter run?
Anything up to 3,000W continuous, with 6,000W available briefly for start-up surges. That covers lights, a fridge, laptops and power tools, and larger loads like a microwave or small air conditioner. The daily total depends on your battery bank, not the inverter.
What size battery do I need?
Work from your daily watt-hours, not the inverter rating. As a rule, a 12V bank should be able to deliver the inverter's full output without exceeding its discharge rating. We can size it with you on 1-332-291-6885.
Can I use it while plugged into shore power?
This model inverts only — it does not charge. For charging from shore or generator power, choose a SUPERCHARGER inverter charger or a hybrid model.
